HMC-AUH249
v04.0909 4 GaAs HEMT MMIC MODULATOR
DRIVER AMPLIFIER, DC -35 GHz Typical Applications Features This HMC-AUH249 is ideal for: Small Signal Gain: 15 dB • Fiber Optic Modulator Driver Output Voltage: up to 8V pk-pk • Gain Block for Test & Measurement Equipment Psat Output Power: +23 dBm • Point-to-Point/ Point-to-Multi-Point Radios High Speed Performance: >35 GHz 3 dB Bandwidth • Wideband Communication & Surveillance Systems Supply Voltage: +5V @ 200 mA • Radar Warning Systems Small Die Size: 2.2 x 1.80 x 0.1 mm Optical & Modulator Drivers -Chip • Military & Space General Description Functional Diagram The HMC-AUH249 is a GaAs MMIC HEMT Distributed
Driver Amplifier die which operates between DC and
35 GHz and provides a typical 3 dB bandwidth of
37 GHz. The amplifier provides 15 dB of gain and
+23 dBm of saturated output power while requiring
only 200 mA from a +5V supply. The HMC-AUH249
exhibits very good gain and phase ripple beyond
25 GHz and can output greater than 8V peak-topeak, making it ideal for use in broadband wireless,
fiber optic communication and test equipment
applications. The amplifier die occupies less than
4 mm² which facilitates easy integration into MultiChip-Modules (MCMs). The HMC-AUH249 requires
a bias-tee as well as off-chip blocking components
and bypass capacitors for the DC supply lines. Vgg1
adjusts the bias current for the device while Vgg2
adjusts the output gain. Electrical Specifications [1], TA = +25 °C, Vdd = 5V, Vgg2 = 1.5V
